Component Testing

Relay Test

1. Ignition OFF, remove the KR99 Air Suspension Relay.
2. Test for 70-150 Ω between terminals 85 and 86.
   • If less than 70 Ω or greater than 150 Ω 

     Replace the KR99 Air Suspension Relay.

   • If between 70-150 Ω 
3. Test for infinite resistance between the terminals listed below:
   • 30 and 86
   • 30 and 87
   • 30 and 85
   • 85 and 87
   • If less than infinite resistance 

     Replace the KR99 Air Suspension Relay.

   • If infinite resistance 
4. Install a 30 A fused jumper wire between relay terminal 86 and 12 V. Install a jumper wire between relay terminal 85 and ground.
5. Test for less than 10 Ω between terminals 30 and 87.
   • If 10 Ω or greater 

     Replace the KR99 Air Suspension Relay.

   • If less than 10 Ω 
6. All OK.
